Surgical outcomes for herniated lumbar discs and stenosis show persistent neurological deficits. While some motor and sensory losses improved, a notable percentage experienced worsened or new symptoms post-surgery.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Neurology

Background:

  • Surgical interventions for lumbar disc herniation and stenosis are common.
  • Assessing long-term neurological outcomes is crucial for patient management.

Purpose of the Study:

  • To evaluate neurological deficits 1 year after surgical treatment for herniated lumbar intervertebral discs and lumbar stenosis.
  • To compare patient-reported and surgeon-reported outcomes.

Main Methods:

  • A cohort of 443 patients undergoing surgery for lumbar disc herniation or stenosis was assessed.
  • Data collected via patient and surgeon questionnaires at 1 year post-operation.
  • Neurological assessment included motor function, sensory perception, and reflexes.

Main Results:

  • Preoperative motor loss (12% patients, 28% surgeons) persisted post-surgery in 24-25% of cases, with 3-5% attributed to surgery.
  • Sensory abnormalities reported by 53% of patients preoperatively decreased to one-third post-surgery, with 12-15% attributed to surgery.
  • Reflex deficits improved significantly, though 3-10% of cases showed surgery-induced or aggravated reflex issues.

Conclusions:

  • Surgical treatment for lumbar disc herniation and stenosis can lead to persistent or new neurological deficits.
  • Patient and surgeon perspectives on neurological outcomes show some concordance but also discrepancies.
  • While many neurological functions improve, careful patient selection and surgical technique are vital to minimize iatrogenic complications.
